--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-06-08 13:38:51 UTC --- Or alternatively make it more dynamic, like if in one function the maximum level is reached or almost reached (so it could be checked only in vt_expand_loc_callback) more than some parameter times (like several millions or so), it would temporarily drop down the limit to a lower value. It would probably need to recheck all var locations at that spot though, because dummy and real expansion should match.
